The inner fuel-tube is smaller than andextends into the outer fuel-tube nearly to its inner end. rllhe innerend of the inner fuel-tube is open, and the inner fuel-tube is connectedat its outer end with the oil-supply pipe B. A

pipe 17 having a control-valve 18, leads from the collar 141,

rThe wall 11 also has another opening in which is secured and from whichprojects outwardly a stufling-box 19. rlfhis stuffingbox carries andforms a fluid-tight joint with a steam-tube 20, which may be movedinwardly and outwardly by loosening parts of the stuffing-box, and whichextends through the lsteam-chamber and into the superheater-casingnearly to its inner end. The steam-tube is open at its inner end, and itis connected at its outer end with the steamsupply pipe A.. A pipe 21,having a controlvalve 22, leads from an exit 23 of the steamchamber. Thesteam-chamber is fitted in its lower portion with a drain-valve 21.

l/Vhen the apparatus is in use, steam under pressure is discharged fromthe steam-tube into the superheater-,casing at its inner end,

and oil under pressure is discharged from the inner oil-tube at itsinner end. r1`he steam fills the superheater and the steam-chambersurrounding the outer oil-tube, and under the influence of the heat ofthe fire-box to which the superheater-casing is subjected the steamtherein is heated to a temperature offrom 1,000 to 1,200 degrees F. Thefluid in the superheater surrounding the oil-tubes in turn heats them,and the fuel contained about twelve feet, the fuel travels a distance ofapproximately twenty feet in passing through the inner and outerfuel-tubes in the furnace, besides being subjected to heat in thesteam-chamber, and this is suflicient to bring the fuel to the requiredtemperature to cause gasification upon liberation. The

fuel andV steam are discharged from the superheater, respectively, intothe pipes 17 and 21. The fuel in the oil-supply pipe is maintained byany suitable means at a constant presure of from 50 to 100 pounds, thepressure being determined by the particular grade ofoil fuel in use, andthe temperature to which the fuel in the superheater is subjected iscontrolled by varying the pressure, and therefor the Volume, of thesteam that transmits heat to thev fuel-tubes, the teniperature beingraised and lowered by invoil and thereby to prevent carbonizationtherein. l

Each ofthe pipes 17 and 21 is fitted with a thermometer-tube 25, thepipes lead to and are coupled into a plate 20 set into the front wall 11and forming the front wall of a burner, and they discharge Ainto amixingchamber 27 contained within a casing 28 threaded at its receivingend into the plate.

The other end of the casing 28 is contractedand integrally joinedwith-the walls of an outwardly-extending discharge-nozzle 29.

Up to the time of their discharge into the mixing-chamber, the -i'iuidsfrom the oil and steam supply are heated and conveyed separately. 1Uponliberation into the mixingchamber, the super-heated fluid from theoiltubes imediately becomes gasified and thoroughly mixed with vaporderived from the steam inthe superheater and the carbon thereofA isassimilated.

The mixture is discharged through the nozzle and is mixed with air drawnthereby from anair-conduit 30 extending through the mixing-chamber andhaving its discharge-end portion extending into the nozzle. rEheair-conduit at its other end is threaded centrally into and extendsoutwardly of plate 26. an air-regulator casing 31, larger than theconduit, is threaded at one end onto the outwardly-projecting portion ofthe conduit, and its other end portionY is exteriorly screw threaded andcarries an interiorly screw-threaded regulator cap 32 having side ports33. 'lfhe open area of the ports, and thereby the amount of air drawninto the conduit, is regulated by turning the cap in one direction orthe other, and the proportion of fuel-gas and steam-vapor admitted tothe mixing-chamber is regulated by the valves 18 and 22, all inaccordance with the grade of liquid fuel in use and the heat required inthe furnace.y

Having thus described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is- 1. A superheater for fluid fuel comprisingan elongated casing closed at one end, a housing closing a steam-chamberhaving an exit connected to the other end of said casing and having anend wall, an outer closed fuel-tube extending through said wall intosaid casing nearly to its other end and having an exit outside of thesuperheater, an inner fuel-tube adapted to be connected With a source ofsupply and extending into said outer fuel-tube and arranged to dischargethereinto nearits inner end, and a steam-tube extending through saidWall into said casing `and arranged to discharge thereinto near itsother end.

2. A superheater for fluid fuel compris'- ing an elongated casing closedat one end, a member screwed onto the other end of said casing andhaving an annular threaded flange, an annular housing screwed onto saidflange and having an end Wall provided With an exit, an outer closedfuel-tubey extending through said Wall into said casing nearly to itsother end and having an exit outside of the superheater, an innerfueltube adapted to be connected with a source of supply and extendinginto said outer fuel-tube and arranged to discharge thereinto near itsinner end, and a steam-tube extending through said Wall into said casingand arranged to discharge thereinto near its other end.

3. In a furnace including a Wall and a ire-box adjacent thereto, thecombination of an elongated superheater-casing extending through saidWall along the bottom of said lire-box, a housing inclosing asteam-chamber having an exit connected to the outer end of said casingand having an end Wall, an outer closed fuel-tube extending through saidchamber-Wall into said casing nearly to its other end and having anVexit outside of said chamber, an inner fuel-tube connec-ted With asource of liquid-fuel supply extending into said outer fuel-tube andarranged to discharge thereinto near its inner end, a steam-tubeconnected With a source of supply extending through said chambervvallinto said casing and arranged to discharge thereinto near its other end,a burner in said furnace-Wall above said casing having Aa mixing-chamberand a nozzle discharging therefrom into said fire-box, a pipe 4. Asuperheater for fluid fuel comprising an elongated casing closed at oneend,

a member screwed onto the other end of said casing and having anannular, threaded ange, a cylindrical housing screwed onto said flangeand inclosing an enlarged steamchamber, said housing having an end Wallprovided with an exit and an opening separate therefrom, a stuffing-boxin said opening, anl outer closed fuel-,tube extending through saidstuffing-box nearly to the other end of said casing and having an exitand an axially-disposed opening outside of said end wall, an innerfuel-tube adapted to be connected to a source of supply and extendinginto said outer fuel-tube nearly to its other end and adapted there todischarge thereinto, and a steam-tube extending through said end Wallinto said casing and arranged to discharge thereinto near its other end.

5. A superheater for fluid fuel comprising a casing having an exit, asteam-discharge pipe leading from said exit, an outer fueltube closedWithin saidv casing and having an exit outside'thereof, a:fuel-discharge pipe leading from said fuel-tube exit, anrinner'fuel-tube extending into said outer fueltube and arranged to dischargethereinto, a steam-tube extending and arranged to discharge into saidcasing, a steam-supply pipe connected to said steam-tube, a fuel-supply.pipe connected to said inner fuel-tube, and a valve-controlled by-passconnecting said supply-pipes.
